5f69a31f	2012-09-24T20:52:34	Initial implementation of new diff patch API Replacing the `git_iterator` object, this creates a simple API for accessing the "patch" for any file pair in a diff list and then gives indexed access to the hunks in the patch and the lines in the hunk. This is the initial implementation of this revised API - it is still broken, but at least builds cleanly.
bae957b9	2012-09-25T16:31:46	Add const to all shared pointers in diff API There are a lot of places where the diff API gives the user access to internal data structures and many of these were being exposed through non-const pointers. This replaces them all with const pointers for any object that the user can access but is still owned internally to the git_diff_list or git_diff_patch objects. This will probably break some bindings... Sorry!
64286308	2012-09-25T10:48:50	Fix bugs in new diff patch code This fixes all the bugs in the new diff patch code. The only really interesting one is that when we merge two diffs, we now have to actually exclude diff delta records that are not supposed to be tracked, as opposed to before where they could be included because they would be skipped silently by `git_diff_foreach()`. Other than that, there are just minor errors.
b36effa2	2012-09-10T09:59:14	Replace git_diff_iterator_num_files with progress The `git_diff_iterator_num_files` API was problematic, since we don't actually know the exact number of files to be iterated over until we load those files into memory. This replaces it with a new `git_diff_iterator_progress` API that goes from 0 to 1, and moves and renamed the old API for the internal places that can tolerate a max value instead of an exact value.
60b9d3fc	2012-09-05T15:00:40	Implement filters for status/diff blobs This adds support to diff and status for running filters (a la crlf) on blobs in the workdir before computing SHAs and before generating text diffs. This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git. Right now it is a #define in src/diff.h but it could be moved into the public API if desired.
f335ecd6	2012-08-30T14:24:16	Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
0abd7244	2012-06-04T16:17:41	Fix filemode comparison in diffs File modes were both not being ignored properly on platforms where they should be ignored, nor be diffed consistently on platforms where they are supported. This change adds a number of diff and status filemode change tests. This also makes sure that filemode-only changes are included in the diff output when they occur and that filemode changes are ignored successfully when core.filemode is false. There is no code that automatically toggles core.filemode based on the capabilities of the current platform, so the user still needs to be careful in their .git/config file.

19fa2bc1	2012-04-17T15:12:50	Convert attrs and diffs to use string pools This converts the git attr related code (including ignores) and the git diff related code (and implicitly the status code) to use `git_pools` for storing strings. This reduces the number of small blocks allocated dramatically.
14a513e0	2012-04-13T15:00:29	Add support for pathspec to diff and status This adds preliminary support for pathspecs to diff and status. The implementation is not very optimized (it still looks at every single file and evaluated the the pathspec match against them), but it works.
95dfb031	2012-03-30T14:40:50	Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.
1db12b00	2012-03-25T23:04:26	Eliminate hairy COITERATE macro I decided that the COITERATE macro was, in the end causing more confusion that it would save and decided just to write out the loops that I needed for parallel diff list iteration. It is not that much code and this just feels less obfuscated.

74fa4bfa	2012-02-28T16:14:47	Update diff to use iterators This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.

It also includes renaming some structures and some refactoring of the existing code so that it could be shared better with the new function. This is not complete since it needs a rebase to get some new odb functions from the upstream branch.

65b09b1d	2012-02-02T18:03:43	Implement diff lists and formatters This reworks the diff API to separate the steps of producing a diff descriptions from formatting the diff. This will allow us to share diff output code with the various diff creation scenarios and will allow us to implement rename detection as an optional pass that can be run on a diff list.
